We are offering high-voltage tuning reactor. structure of high-voltage tuning reactor the iron core of our company dry-type iron-core series reactor using high quality imported silicon steel, the core columns is divided into uniform pieces by the number of air-gap , the air gap isolated by epoxy fabric panels , in order to ensure gap do not change when the reactor operate in long-term . ã¢ï¿½â¢iron core using high quality silicon steel end face gule, so silicon steel firm together , which reduces the running noise greatly , dust-proof and moisture-proof function with a good performance. ã¢ï¿½â¢coil is epoxy cast type, both inside and outside laying epoxy glass grid cloth to intensification, the system using class f epoxy for casting under vacuum, the coil is not only good insulation, but also high mechanical strength, can withstand high current impact and thermal shock without cracking. Epoxy cast coil is non-absorbent, partial low discharge, can be operated safely in harsh environments. Upper and lower ends of the coil using epoxy and silicone rubber for shock pads, effectively reduces shock when the coil running.

We are offering Filter Capacitor. Filter capacitor adopts double-sided thick polypropylene film as the solid medium, benzyl toluene (m/dbt) Or phenyl ethane (pepe) as a liquid medium. In order to fold aluminum foil plate, introduce into foreign advanced technology. Equipment production is accordance with national standards IEC in strict , mainly for the circuit of harmonic filter device. Features 1 low-temperature Harmonic filter circuit composed by capacitor serial reactor, formed minimum impedance In a certain harmonic order times to absorb large amounts of harmonic current. The quality of the capacitor can affect the stability of the harmonic filter absorption effect, the life of the capacitor has a great relationship with temperature, the higher the temperature the lower life . Full-film filter capacitor has a low temperature characteristics which can guarantee its service life. (2) low loss Dielectric loss tangent (tgδ): ≤ 0.0003; 3 security In line with GB, IEC standard, protection devices installed in a single-capacitor attached to the internal; when an exception occurs in a circuit or single-capacitor , the protection device will be an immediate action, automatically cut off power to prevent a secondary disaster. Attached to the discharge resistor, to ensure safety of electricity and maintenance . Shell made of pressed steel, painted lacquer baked high temperature inside and outside which has good weather resistance ability, so it has high security. 4 convenience Small size and light weight, easy to install and carry The main technical indicators Rated Voltage: 1 ~ 12kv, ac; Rated frequency: 50hz; Rated capacity: 30 ~ 200kvar; Capacitance tolerance: -5% to +10% Dielectric loss tangent (tgδ): ≤ 0.0003; Maximum allowable over-voltage: 1.1un; Maximum allowable over-current: 1.3in; Self-discharge characteristics of built-in discharge resistance: Ambient air temperature: -40 ~ +45 ℃; Altitude: ≤ 1000m; Environmental conditions: No harmful gases and vapors, conductive and explosive dust.

If you need to compensate for power factor and installed capacitors in a equipment system with harmonic source, transformers and capacitors may lead to harmonic resonance. In order to avoid harmonic resonance, we can series a tuning reactor before a capacitor . The designed frequency of tuning capacitor reactor must be set much lower than the lowest-order harmonic frequency of the system, so that you can compensate for reactive power at the fundamental frequency (50hz) , and there is no risk of harmonic resonance. Main features of three-phase reactor: 1 iron core use the high quality low-loss import cold rolling silicon steel slice , core columns evenly divided into small pieces by a number of air-gap , air-gap isolation using nomex insulation paper , to ensure reactor during operation of the air gap does not change. 2 reactor coil is insulated from the h-grade enamelled copper wire.arrangement is close and even , appearances arenã¢ï¿½ï¿½t bag insulating layer, with excellent aesthetic and better heat dissipation. 3 reactor coil and core assembly into one after pre-flood ã¢ï¿½ï¿½ vacuum impregnation ã¢ï¿½ï¿½hot baked curing ã¢ï¿½ï¿½ technological process, using the h-grade varnish, make the reactor core and coil firmed together, not only greatly reduces the running noise, but also has a very high heat-proof level, to ensure reactor can also run at high temperatures safely and without noise. 4 the reactor core column use non-magnetic materials to ensure that the reactor has a high quality factor and low temperature-rise, to ensure a better filtering effect. 5 the reactor deal with natural air cooling, the exposed parts are took anti-corrosion treatment, terminals use of tin-plated brass , through product testing and the tests for all procedure, to ensure the productã¢ï¿½ï¿½s performance parameters of consistency, all materials fits the standards of ul, sgs .

While a large number of modern power electronic equipment used(such as: variable frequency drives, etc.) , the nonlinear current generated by harmonic way affect the power grid and to increase the power load. The capacitor and transmission transformer in traditional system of pure power factor correction capacitors connected to the resonant circuit .Resonance may cause capacitor overload , which is bad for measuring and controlling the system of interference, voltage-distortion, harmonic amplification. The use of tuning reactors and capacitors in series to form a power factor correction system can be tuned to avoid resonance
